DAM.

To all whom it may concern:

Be it known that I, Gorrmnn Mnnnnnisnn, a citizen of the United States,residing at Alma, in the county of Buffalo and State of WVisconsin, haveinvented new and useful Improvements in Dams, of which the following isa specification.

The primary object of this invention is the provision of means forretarding and catching material while at the same time permitting waterto flow freely through a ditch, trench or like water course.

The invention provides an obstruction in the nature of a dam which inpractice will prevent ditches from getting deeper or longer and whichwill change the course of the stream and which further will fill ditchesat the lower end when such ditches carry mud or any other trash, suchmatter lodging against the dam and remaining there while the water willflow through the obstruction, such dam holding the filling even thoughthe same be fine, clear quick sand.

The invention provides a dam which pessesses a certain amount offlexibility and which may be easily placed in position, the samecomprising panels or sections arranged to extend across the bottom andalong the sides of the ditch, such dam comprising stakes which aredriven into the ground, means for holding the stakes properly spaced anda filling such as a cable which is interwoven with the stakes.

Further objects of the invention will ap' pear as the followingdescription is read in connection with the accompanying drawing, whichforms a part of this application, and in which Figure 1 is a front viewof a dam embodying the invention. Fig. 2 is a top plan view partly insection. Fig. 3 is an enlarged horizontal section of one of the panels.Fig. 4 is an enlarged transverse section.

Corresponding and like parts are referred to in the followingdescription and indicated in all of the views of the drawings by thesame reference characters.

As indicated, the dam comprises a plurality of sections or panels A andB, the middle panel A extending across the bottom and the side panels Bextending across the sides of the trench, ditch or other water course.The several panels or sections are of similar formation and are flexiblyconnected. Cables 1 act as stays to retain the dam in place. Each panelor section of the Specification of Letters Patent.

Patented Nov. 3, 191.4.

dam comprises a plln-ality of stakes 2 which are driven into the bed ofthe ditch or water course. Angle bars 3 and t serve to hold the stakesproperly spaced, such bars having openings in one of their wings, theother wings extending along the sides of the stakes. The angle bars havean opposite arrangement, that is, the horizontal flange or wing of oneof such angle bars projects upstream and the flange or wing of the otherangle bar projects downstream. The space between the stakes and anglebars is filled by means of a cable 5 which is interwoven or interlacedwith the stakes, thereby forming a net or screen which obstructs thepassage of filling material while admitting of the water passing freelytherethrough.

The adjacent stakes of contiguous anels or sections are connected bymeans of rings 6 to hold them in alinement. Any means the equivalent ofthe rings 6 may be employed so long as they serve to connect the stakesof adjacent sections and prevent separation.

\Vhen constructing a dam in accordance with this invention the stakes 2are driven into the ground a proper distance apart and extend the fullwidth of the ditch, trench or water course. The angle bars 3 and 4:serve to space the stakes and hold them in fixed relative position.After the stakes have been properly positioned the space between themand the angle bars is filled by means of the cable 5 which is interwovenor interlaced in a manner well understood and as clearly illustrated inthe accompanying drawing.

From the foregoing description, taken in connection with theaccompanyingdrawing, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the device whichI now consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of the claimsappended hereto.

It is to be understood that the device may be used as a fence and thatthe filling elements 5 may consist of wire. The article may be factorymade and the panels may be of any relative length and type. It isfurther noted that the stakes 2 are adapted to slip through theinterlacing of the cables,

Wires or like filling elements 5, thereby admitting of such stakes beingdriven into the ground or bed of the ditch or the like.

hat is claimed is A clam for Water courses, the same comprising aplurality of panels to extend along the bottom and sides of the Watercourse, each panel being of similar formation and comprising a pluralityof stakes and upper and lower angle bars having the stakes passingthrough the horizontal flanges thereof, said stakes having thelr lowerends driven into the bed of the Water course and the contiguous stakesof adjacent panels being connected, a filling interwoven With the stakesof each panel between the upper and lower bars thereof and stays forholding the several panels in position.

In testimony whereof I affix my signature in presence of tWo Witnesses.
